Oh, and by 2 cents on prohormones of all flavors...
Something can be a steroid if its molecule has certain structural qualities, but that doesn't make it an ANABOLIC steroid. A lab in he Bay Area is is HUGE trouble because htey had developed a designer ANABOLIC steroid that didn't show up in blood tests. The government is QUICK to crack down on anabolic steroids, and if half that hype about "T-Bomb" was true they'd be shut down.
Prohormones have had a suspicous lack of truly scientific testing. Those tests that have been done by people with MDs and PhD isntead of "B.H.Sci HMS"s seem to indicate they don't do much. DHEA and Androstenendione raised ESTROGEN levels but not TESTOSTERONE levels in the "real" tests. This is why the FDA doesn't regulate them, because they're pretty much harmless and useless.
Of course, I am an old, bitter, ironhead who's seen too many "THIS WILL CHANGE EVERYTHING" supplements not change anything. YOU DARN KIDS, GET OFF MY LAWN!
